Add basic support for initialized globals.
* parse.cxx (parse_global): Parse initialization clause, implement
by rewriting to "probe begin { var = value }".

* translate.cxx: Added inclusion of session.h.
(translate_pass): Instead of asking each probe to emit itself, we
ask the session's probes member variable to emit all the probes.
* tapsets.cxx: Added inclusion of session.h. Added a
register_probe member function to all derived_probe based
classes. Added a derived_probe_group derived class for all probe
types:
(be_derived_probe_group): New class.
(never_derived_probe_group): New class.
(dwarf_derived_probe_group): New class.
(timer_derived_probe_group): New class.
(profile_derived_probe_group): New class.

* elaborate.h: Removed inclusion of session.h since session.h now
includes elaborate.h.
(derived_probe): Added register_probe member function.
(derived_probe_group): Added class definition. This is the base
class of all of the derived probe groups - dwarf, timer, etc.
(derived_probe_group_container): Added class definition. An
instance of this class will be stored in the session and contain
all the other probe groups.
* elaborate.cxx (derived_probe_group::register_probe): Added
derived_probe_group::register_probe stubs.
(alias_derived_probe::register_probe): Added register_probe member
function.
(semantic_pass_symbols): After deriving a probe, the probes now
register themselves with the session.
* session.h: Includes elaborate.h to get
derived_probe_group_container definition. systemtap_session class
'probes' member variable switched from a vector of derived probes
to a derived_probe_group_container.
* buildrun.cxx: Added inclusion of session.h since it was removed
from elaborate.h.
* main.cxx: Added inclusion of session.h since it was removed
from elaborate.h.
* parse.h: Added forward struct declarations.
* staptree.h: Removed inclusion of session.h.
